.1 Be it known that I, ISAAC W. FISHER, a citizen of the United States, residing at ,Escondido, in the county of San Diego and State of. California, have invented certain new and useful Improvements in Concrete Forms for Log Cabins; and I dohereby declare the following to be a full, clear, and exact description of the invention, such'fas will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to a frame or mold for forming a log-cabin ofl concrete or analogous materiahthe mold being of sectional formation and adapted to ybe readily set up and easily taken apart after thestructure has set. f

-Otlier objects and advantages will be apparent and suggest themselves as the nature of the invention is understood. f i

Vhile the drawings illustrate an embodinient of the invention it is to be understood f that in adapting the same to meet different conditions and requirements, various changes inthe form, proportion and minor details of construction may be resorted to provided they `fall within the spirit and scope of the invention as claimed.

- Referring to the accom anying drawings forming a part of the app ication Figure 1 is a horizontal sectional view of a concrete mold embodying the invention,

Figure 2 is adetail perspective view of a corner portion of the mold and structure,

Figure 3 is a diagrammatic view of a corner portion of the mold extended,

Figure 4 is a view similar to Figure 3 showing the reverse side of theparts,

Figure is a detail sectional view on the line 5-5 of Figure 1, andv Figure 6 is a detail sectional view on the v line 6 6 of Figure 1.

Corresponding and like parts are referred nated in the several views of the ldrawings by like reference characters.

It is to be understood that the general outline of the mold will depend upon the charaacter of the structure to be formed and as shown the frame comprises inner sections 10, outer secions 11 and corner sections 12 and 13. The inner sections may consist of boards or plates which are retained in place by posts 14 which, as shown, are disposed at The outer sections 11 are disposed opposite the respective inner sections 19241, .sei-rarita. 714,632."y

FEI-CE# spoiiding to the thickness of thejwalls'fithe i structure.` rlfhe faces ofthe sectioiismay'be or any vform according to therequired surface of the vstructure and `inft'he presentin-v stance, the molding-faces ofthe inner sections .i 10 are'plane, whereasthejinolding' 'facesof thev outer sections 11 'arey 'loi'igitudinally grooved or channeled to correspondwitlitlie appearance of thevouter surface of a log.. cabin. Gpposite outer sections 11 .have end extensions 15 which are plain, the-shoulder v o r abutment at the inner endk of the extension 15 being notched as indicated at 16, said 'notches being half-round tocorrespond withV one-half of the cuter projections representing the ends of the logs beyond the notched joints. The other two outer sections 11 terminate in straight or square ends vwhich abut the adjacent'corner sections 13. End strips 17] and 18 reinforce and strengthen the ends ofthe outer sections 11. The corner sections f 1 2 and 13 are hinge'dly connected as'indicated' at 19, and the sections 12 are hinged to the extensionsl 15 of the adjacent outer section 11, as indicated at 20, latches 21 being provided to secure the corner sections 13 to the' tion 11. The molding faces of the corner to match the grooved or channeled faces of reinforceden'ds'of the adjacent outer secthe outer sections in line therewith and their i -opposededges are cut away and notched, as indicated at 22, tokform projections corresponding to theprojecting endsof` logs, the projectingend onzlone side being formed between the Anotched edges22 and the projecting'ends at the opposite side being formedbetween the notched portion 16 of an outer section 11 and thefgrooved face of thesec.- tion 12 hinged thereto.4 When the form isset up, a space isprovidv -ed between the several sections and this space to in the following description and desig-` receives the concrete or other material' from which the structure is to be formed, said material being suppliedtothe space and tamped therein if necessary. After the material has set, .the vlatches 21` are released therebyl admitting of easy. removal of the outer sections, the inner sections vbeing removable 4in any convenient and preferred way.

What is claimed is:

1. A mold for forming a structure of concrete, the saine comprising spaced inner and outer sections andcorner sections, the latter being hingedly connected to'one another and to adjcent ends of the outer sections, and means detnciiablykconnecting the free edges of the corner sections to the free edges of the adjacent outer sections. Y i

2. A mold for forming a structure of concrete, the same comprising inner and outer sections, corner sections hinged to one another and to the ends of djacent outer siections, and latches connecting ythe free corner sectionsfttlie free edges of the adjacent (intersections. y, v Y j 3,: A nold fdr forming a lo cabin, the srnecomjirising outer sections wing their. ildingwfecfe's longitudinally grooved, one of the sections having n extension and the sholdlxtils frh'ld notched; Corner SeC- t'ions hinged to one another and to the extensions of the respective outer sections, the molding' faces of the corner sections being grooved or channeled and their opposing edges being cut away and notched to forma.

grooved face of the corner section hinged to t said extension.
